PHOENIX -- Milwaukee Brewers right-hander Zack Greinke is likely to begin the season on the disabled list because of a fractured right rib.
Greinke injured himself while playing basketball in the offseason. Initial X-rays were negative, but an MRI exam Monday revealed a hairline fracture in one rib and a bruise in a second.
Greinke is a former AL Cy Young winner. The Brewers acquired him in an offseason trade with Kansas City.
